Abstract

Identifying relevant stimuli that will help generate solutions of desired novelty and quality is challenging in analogical design. To quell this challenge, this research studies the multifaceted effects of using stimuli located at various analogical distances to the design problem domain(s) on the novelty and quality of concepts generated using the stimuli. Data from a design project involving 105 student designers, individually generating 226 concepts of spherical rolling robots are collected. From these data, 138 concepts generated with patents as stimuli and the patents used as stimuli are analyzed. Analogical distance of a patent is measured in terms of knowledge similarity between technology classes constituting the patent and design problem domain of spherical rolling robots. The key observations are: (a) technology classes in closer rather than farther distances from the design problem are used more frequently to generate concepts, (b) as analogical distance increases the novelty of concepts increases, and (c) as analogical distance decreases the quality of concepts increases.
